The TS-SER4 supports 4 UARTs as RS-232, RS-485, or RS-422.
Refer to the TS-SER4 manual for hardware documentation.
The TS-SER4 implements 16550A based UARTs which require a kernel driver.
Under Linux this requires a device tree change. See the Kernel compile section for more details about getting set up the compile the kernel.
For example, with the IRQ2,IRQ6, and COM1 jumpers installed.
Open the device tree at arch/arm/boot/dts/imx6ul-ts7250v3.dts:

reg = <0x50 0x4>;
ranges = <0 0 0x1000>;
reset-gpio = <&gpio3 7 0>;
#address-cells = <0x1>;
#size-cells = <0x1>;
status = "okay";
/* COMA */

compatible = "technologic,ts16550";
